Wow
That is beautiful - a lady at one of the workshops I attended brought something similar to the show & tell, it was amazing.
Now I think the fabrics she used if I remember correctly were heathers & purples she did as Klue suggested & quilted in gold metallic. It made everything really stand out.
Good Luck - can't wait to see it finished. Is there a prize involved or is it to raise funds for a charity?
